They need some good quality strong boundary fences like we have in HKIA.
I've walked around the fence there many times and there is no way anything smaller than a Tank could bust through.....
I've got some photos of the fence but cannot upload them here.
The fence has about 3 feet of concrete at the bottom, an open area covered with detectors and cameras then another smaller fence. The concrete at the bottom would stop a car or truck. ( maybe not a tank!! )
